Abstract (en)
Disclosed is a photovoltaic module (1,2) comprising several serially connected IBC solar cells (100,200,300), wherein each IBC solar cell (100,200,300) has an electrode structure comprising both a P-type contact electrode structure including at least one P-busbar (112,114,212, 214,312,314) and an N-type electrode structure including at least one N-busbar (116,118,216,218,316,318), wherein at least two of the IBC solar cells (100,200,300) are arranged relative to each other in a partly overlapping manner so that a first region of a back side of a first IBC solar cell (100) is arranged on top of a first region of a front side of a second IBC solar cell (200) and thus creates an overlap region (10,20), wherein at least sections of both the at least one P-busbar (112,114,212,214,312,314) and the at least one N-busbar (116,118,216,218,316,318) of the electrode structure of said first IBC solar cell (100) are located outside of the overlap region (10,30) .
